 <a name=preloading><b>Preloading</b></a> The Preload program from Behdad Esfahbod (a result from SoC2005) was tried again and after two reboots it showed a <b> 2 second </b> time improvement. mapprefix  and exeprefix were set to empty such that all files would be accepted. The results were compared with mapprefix being <a href=log/dirpreload> set to the directories </a> used by some of the init scripts (strace -f initscript), adjusting the quantum time of preload (cycle parameter) and changing the position of the initscript to start just after hwclockfirst.sh. The results were the same: a <b> 2 second</b> time improvent. See the <a href=bootchart_sidKtip_preload.png>bootchart of preload accepting all files</a><a href=bootchart_sidKtip_preload.tgz>(tgz)</a>and  <a href=bootchart_sidKtip_preload2.png>the bootchart with a selected set of directories from mapprefix</a><a href=bootchart_sidKtip_preload2.tgz>(tgz)</a>. The boot of the reference system requires 53 seconds <a href=bootchart_sidKtip_060720.png>(png)</a><a href=bootchart_sidKtip_060720.tgz>(tgz)</a>.

-<p><a name=preloadcompare>Preload 0.2 and 0.4</a> were compared with no good results. See <a href=log/preloadcompare>log file</a>. For preload 0.2 the <a href=bootchart_debiansid_linux2.6.16_060809_preload0p4Default.png>default</a> gave 1 second more while <a href=bootchart_debiansid_linux2.6.16_060809_preload0p4Modified.png>the modified configuration</a> showed no time difference.

+<p><a name=preloadrepeat>Preload test on fresh install</a> Just preload 0.4 was installed with the same configuration as in the preload comparison above. With the default configuration, after one reboot the time was 1 second slower. See <a href=bootcharts/bootchart_debiansid2_preloaddefault.png> bootchart</a>. The modified configuration <a href=bootcharts/bootchart_debiansid2_preloadmodified.png> bootchart</a> behaves similar.

 <p>
 <a name=verbose><b>Less verbose</b></a> The verbose option from the file /etc/default/rcS was changed to "VERBOSE=no" and "VERBOSE=quiet" but the effect was a one second longer boot time. See the <a href=bootcharts/bootchart_debiansid2_notverbose.png>bootchart with "VERBOSE=no"</a> and  <a href=bootcharts/bootchart_debiansid2_quietverbose.png>bootchart with "VERBOSE=quiet"</a>.The boot of the reference system requires 52 seconds <a href=bootcharts/bootchart_debiansid2_original.png>(png)</a>.
